The optical fiber laser cutting machine has performed well in recent years, received extensive attention and praise, and developed rapidly. The optical fiber laser cutting machine is popular in the manufacturing industry because of its wide application field, high processing efficiency, smooth cutting surface and no burrs, not limited to graphics and other advantages.
However, no matter what kind of machinery, there will be big or small problems. Today, let’s talk about why the fiber laser cutter cuts holes irregularly and what causes it.

That is because when laser piercing is used, a certain blasting phenomenon usually occurs due to the burning through of the penetrated materials due to the high power and slow speed. Because of this blasting phenomenon, the cut holes will naturally appear irregular.

What other reasons are there?
1. Hole too small
Although the speed of laser light is small, cutting also has parameters. It is better to cut circular holes at a ratio of 1:1. No matter what machinery, there is a limit value, because it is related to the travel limit and the head. Otherwise, when the energy of the fiber laser cutting machine is insufficient, it is easy to cut small holes with broken points and round holes that are not round.
2. Servo motor parameters
The parameters of the servo motor are wrong. In fact, many parameters of the servo motor are related to the arc movement. The error of the parameters will cause the cut hole to become elliptical or irregular.

3. Guide screw
The precision of the guide screw is not enough. Some manufacturers are not strict enough to meet the requirements, or impurities enter the guide screw to wear it, thus affecting the precision.
Therefore, the machine should also be maintained regularly to remove residues and add lubricating oil again, so as to ensure the accuracy of the machine and extend its service life.
4. Barometric pressure
In the process of blowing, if the air pressure is too low, slag hanging, carbonization and roughness will occur, and if the air pressure is too high, holes will be easily burst. Therefore, it is also one of the methods to solve the irregular cutting of round holes to adjust the appropriate pneumatic pressure.
